NDS 3 in. - 4 in. Plastic Round Drainage Grate in Black (11U)

About This Product
Efficiently manage surface water while preventing debris and leaves from clogging your drainage system. The 4 in. Round Drain Grate is designed to cover drain pipes and effectively drain light stormwater flows from small lawns, patios, walkways, and landscaped areas. This grate, with an open surface area of 2.4 sq. in. and a flow rate of 7 GPM, connects seamlessly to 3 in. & 4 in. sewer and drain pipes, fittings, single-wall corrugated pipes, and triple-wall pipes for a secure, soil-tight fit. ADA-compliant and heel-proof, it’s made from durable polyethylene with UV inhibitors to protect against cracking and fading. As part of a complete drainage system, the grate helps block debris from entering pipes, which then carry the water to a downstream discharge point like a pop-up emitter or dry well. Use the NDS Home Drainage Center tool to find the best drainage solution for your project. Founded in 1972, NDS is a trusted leader in stormwater management, offering proven products and expert support.
